Another good guideline while shopping is to have your ideal price ranges in mind. Put limits on what you would spend on a particular item.
For instance, no matter where I shop my limit on a blouse is $15, jeans is $35, shorts is $15, skirt is $15, dress is $30. I also have price limits on different styles of shoes. If I walk into a store with those guidelines in place, then I am more likely to be satisfied with my purchases. Of course, every now and then I do go out of those ranges, but usually it’s because I have been searching for a particular item for so long that I know I probably won’t find it again. Or I know I’ve been getting super deals lately and I will splurge on an item. Or I find an item that is so amazingly cute that I am willing to spend a little more. Usually the third case doesn’t happen too often because I reason with myself that that price is just ridiculous for that item and just walk away admiring it. Then I never remember what it even looks like, so I don’t miss it.
So, I suggest that you figure out what your price limits are before you go shopping. Ask yourself what prices would you be happy to spend on an item and feel satisfied, not guilty? If it is pricier, will you get a lot of wear out of it? There are stores I go into and walk out empty handed because the clothes I picked didn’t fit my price criteria or I just couldn’t find anything I liked :P Personally, I’m a happier shopper buying cute clothes for dirt cheap.
